Abstract

The shortwave radiative impacts of dust based on spherical and spheroidal dust particles are compared. For spheroids, two different shape distributions are considered. The size distribution, optical thickness, and the solar zenith angle are varied and the dust is assumed to reside over an ocean. At the top of the atmosphere the radiative impact computed with spheres and spheroids differs by up to 12%.
